NCollection_StlIterator< Category, BaseIterator, ItemType, IsConstant > Class Template Reference

Helper class that allows to use NCollection iterators as STL iterators. NCollection iterator can be extended to STL iterator of any category by adding necessary methods: STL forward iterator requires IsEqual method, STL bidirectional iterator requires Previous method, and STL random access iterator requires Offset and Differ methods. See NCollection_Vector as example of declaring custom STL iterators. More...

Detailed Description

template<class Category, class BaseIterator, class ItemType, bool IsConstant>
class NCollection_StlIterator< Category, BaseIterator, ItemType, IsConstant >

Helper class that allows to use NCollection iterators as STL iterators. NCollection iterator can be extended to STL iterator of any category by adding necessary methods: STL forward iterator requires IsEqual method, STL bidirectional iterator requires Previous method, and STL random access iterator requires Offset and Differ methods. See NCollection_Vector as example of declaring custom STL iterators.
